  B) Model based on the belief that health status is determined by the interaction of the characteristics of the host, agent, and environment
  C) Study of the distribution and determinants of states of health and illness in human populations
  D) Epidemiologic model that strongly emphasizes the concept of multiple causation while de-emphasizing the role of agents in explaining illness

Answer to Question 1

Ans: C
Feedback:
Epidemiology is the study of the distribution and determinants of states of health and illness in human populations. An epidemic is an outbreak that occurs when there is an increased incidence of a disease beyond that which is normally found in the population. The epidemiologic triad is a model based on the belief that health status is determined by the interaction of the characteristics of the host, agent, and environment. The web of causation is an epidemiologic model that strongly emphasizes the concept of multiple causation while de-emphasizing the role of agents in explaining illness.

Answer to Question 2

Ans: B
Feedback:
Rate is the primary measurement used to describe either the occurrence or the existence of a specific state of health or illness. Natural history is the course of a disease or condition from the onset to resolution. Risk is the probability or likelihood that a disease or illness will occur in a group of people who presently do not have the problem. A risk factor is a characteristic or event that has been shown to increase the probability that a specific disease or illness will develop.
